Problems solved by technology

Although the method of manually modifying the array element weights to adjust the direction diagram is simple, because it is difficult to know the modified results in advance, this method is accidental and the efficiency is also low
In the case of a large number of array elements, it also takes a long time
The traditional shape-forming algorithm focuses on the optimization of the overall goal, and the optimized pattern may have problems such as partial substandard or inaccurate pattern.

Abstract

The invention relates to an antenna array arbitrary beam micro-shaping tool and an implementation method, and the tool comprises: a data initialization interface system which is configured to import array antenna parameters; a beam adjustment interface system which is configured to adjust an antenna pattern and then dynamically update a corresponding weight or dynamically update the corresponding directional diagram after the weight is adjusted; and a data export system which is configured to export the weight corresponding to the adjusted directional diagram in a text format. According to the beam micro-shaping tool provided by the invention, fine tuning can be carried out on the directional diagram obtained by a shaping algorithm, the weight corresponding to the fine-tuned directional diagram is obtained, any desired directional diagram can be obtained through the fine tuning theory, the function substantially breaks through the design requirement of an excitation optimization algorithm, and great convenience is brought to antenna design workers.

Description

technical field [0001] The invention relates to an antenna array arbitrary beam micro-shaping tool and a realization method, and relates to the field of antenna pattern beam forming. Background technique [0002] In recent years, beamforming (Beamforming) technology has been extensively studied. The so-called beamforming technology, also known as beamforming and spatial filtering technology, is a technology for processing transmitted signals and received signals. When the beamforming technology is applied to the antenna, by adjusting the excitation applied to each element of the array antenna, a specific form of pattern can be synthesized, so that the pattern can be aligned in the required direction and the efficiency of the antenna can be improved. According to wave theory, the far-field pattern of an array antenna can be regarded as the vector superposition of the far-field pattern provided by each array element in the array. In the study of beamforming, by reasonably se...
